Flight MH370: Authorities very close to finding jet

A FINAL unexplained signal emitted by the missing Malaysia Airlines plane was tracked to the same point in the Indian Ocean at which authorities believe they have found the jet, it can be revealed.

It is thought that this final "half-handshake" - or satellite contact - could have been the moment at which the plane ran out of fuel and plunged into the ocean.

As authorities said they were "very close" to finding the plane after detecting more than two hours of underwater signals,

The Daily Telegraph learnt that the site coincides with analysis from two weeks ago, which estimated where the final contact occurred.

The breakthrough in the search has assisted analysts to gain a picture of the likely final sequence for the aircraft, which is believed to have run out of fuel and then experienced a last jolt of power that triggered an incomplete satellite handshake before entering the water.

In such a scenario, the plane would likely to have glided and could have turned upside down - rather than plunging into the water.

Angus Houston, who is coordinating the multinational search, said an Australian navy ship had detected two sets of pulse signals that sounded "just like an emergency locator beacon". The development was, he said, a "promising lead".

The first set was heard on Saturday and lasted for two hours and 20 minutes. The Ocean Shield ship then lost contact with the "pings'' but turned around and later heard further signals for 13 minutes. It has since lost contact again and was trying last night to relocate the signals.

Significantly, Mr Houston said, the second set included two distinct sounds that would be consistent with transmissions from separate pingers attached to the black box's flight data recorder and cockpit voice recorder.

The new signals are not believed to be related to those detected by a Chinese ship about 555 kilometres to the south.
